It was the battle of Christina’s soul men, and what better song to exercise the rock/soul edge in Josh Logan's and Michael Lynch's voices than a hit from coach Adam and his band Maroon 5. Christina and her mentor Ed Sheeran (swoon) felt “Harder to Breathe” would be the perfect track to entertain the audience, and make for an epic battle.

After convincing Josh and Michael to actually perform the song (it looked like a rough rehearsal) the guys connected with the audience and delivered a performance that would impress Christina and the man who wrote the song, Adam Levine. Only one could move on, and in the end it was Josh Logan and his distinct vocals that secured him a spot in the knockout rounds.

Team CeeLo: Juhi vs. George Horga Jr.“Best I Ever Had” by Gavin DeGraw

Juhi and George Horga Jr. had to be “young and fresh” during their performance of Gavin DeGraw's “Best I Ever Had.” Coach CeeLo felt this would be the perfect chance for the 16-year-old high schooler and the 19-year-old that chose to skip college to pursue his dream.

And they did. In one of the most exciting performances of the night, Juhi used her unique vocals while George performed with charm to the audience and coaches (except for Adam, who believed there were a few hitches during the performance). In a surprise to everyone, George gained a spot in the knockout rounds on Team CeeLo, and Adam who hit his big red button to steal Juhi.

Leave it to Blake and his mentor Cher to pick a song not from this decade. During rehearsals, both of the guitar-slinging bluesmen had to find the connection and the power within and go — how did Cher say it? — “balls to the wall” during the performance of such a classic crossover song. Brian got rid of his guitar and put all of his focus into singing without his security blanket. While Brian delivered a straight vocal performance, Austin was able to wow the coaches more, and sending him on to the knockout rounds.

We have learned the pros and cons that come with singing a song by a coach or mentor. The biggest pro: During rehearsal you have the advantage of getting first-hand insight on how to perform the hit. Biggest con: Obviously, the nerves.

This was the case when Adam suggested his two comeback kids James Irwin and Matt Cermanski perform mentor Ryan Tedder and his band OneRepublic’s “Counting Stars.” Matt hit a little bit of an awkward note, but managed to pull himself together after and continue without flaw. James entertained the crowd but still had a few flaws in his voice. Adam mentioned that although it was a flawed performance his decision would still be tough. He chose James, due to his ability to bounce back and work harder to fix his flaws.

Team Christina: Destinee Quinn vs. Lina Gaudenzi“Not Ready to Make Nice” by The Dixie Chicks

It was the time for two of Christina’s sweetest contestant to get mad as hell and pull off the vocal and emotional performance of their lives. During rehearsals Christina and mentor Ed Sheeran pushed the girls to their emotional and vocal limits. (Christina also performed the hell out of the song, making us wish she would have grabbed the mic and got on stage, too). When it came down to the actual performance, Lina’s vocals and Destinee’s emotion made for one of the best battles of the night. The other coaches loved the performance and Christina “lived for it.” Emotion won over all as Destinee was announced winner, and Lina made her way to Team Adam after a steal.

Team Adam: James Wolpert vs. Will Champlin“Radioactive” by Imagine Dragons

Just when I thought I was tired of hearing this song, James and Will changed the game. While the song fit Will more with his vocals and image, James surprised coaches CeeLo and Blake. After a strong vocal battle between both men, Adam picked the man in the sweater, James Wolpert, and Christina decided to give Will Champlin a second chance with the last minute steal.
